The European Union(EU) standard is applied to the emission standards of domestic diesel vehicles, and the emission standards for large-sized diesel vehicles are also introduced and strengthened in stages from Euro 1 to Euro 6, thus reflecting the domestic situation. In large diesel vehicles, mass-produced natural regenerative DPFs often clog DPFs due to regenerative condition failure, resulting in increased ash accumulation, insufficient output, and excessive exhaust emissions. As a result, the inspection failure rate of large diesel vehicles increased, resulting in an increase in unnecessary maintenance costs for consumers, including unexpected DPF cleaning expenses during re-inspection, and social costs for improving the atmospheric environment. Therefore, it is necessary to reflect only the combined regeneration method that can forcibly regenerate vehicles with excessive exhaust emissions among Euro 4 and Euro 5 heavy-duty diesel vehicles, and to expand support for installation costs subject to the installation of PM-NOx reduction devices. If system improvement is implemented as a way to further strengthen the inspection system afterwards, the effect of actively coping with the air environment improvement can be obtained. In conclusion, it can be used as a virtuous cycle tool for social cost benefits, as it can lead to a decrease in medical expenses and a decrease in DPF cleaning expenses due to an increase in human life expectancy.
